Question

If the radius of a sphere is triple, what is the ratio of the volume of the new sphere to that of original balloon.

Answer 1

ANSWER = volume of sphere is:4/3×pi×r cube .

if r- radius is trebled it become( 3r) cube =27×r cube=27 time the original volume . if radius is a triple then value is increase by 27 time.

if radius of sphere is 12 cm 27, sphere of radius melted and recast to form a new solid sphere.
